Title: Methods and systems for selecting quantisation parameters for deep neural networks using back-propagation
Inventor: SZABOLCS CSÉFALVAY
IPC: G06N3/08
Filed: 2018-12-21
Abstract: A Deep Neural Network (DNN) comprises quantisation blocks to transform values input to DNN layers prior to processing, the transformation of the values simulates quantisation to a fixed-point format defined by quantisation parameters. The quantization parameters are identified by: determining 502 an output of a DNN model in response to training data; determining 504 a DNN cost metric based on the determined output and a DNN size based on the quantization parameters; back propagating 506 a derivative of the cost metric to the quantisation parameters to generate a gradient of the cost metric for each parameter; and adjusting 508 the quantisation parameters based on the gradients. Adjusting comprises stochastic quantization or adding a number based on the gradient to generate a modified quantisation parameter and rounding it to a nearest integer. Adding quantization blocks to floating‑point DNNs allows quantisation parameters (mantissa bit lengths and exponents) to be determined via back-propagation.

Title: Optimization of rolling elements on drill bits
Inventor: SHILIN CHEN
IPC: E21B10/43
Filed: 2017-06-15
Abstract: A drill bit includes a bit body having cutters and a generally cylindrical rolling element secured thereon. The rolling element protrudes from the bit body to engage a geologic formation. The location and orientation of the rolling element may be selected such that an outer surface of the rolling element maintains multiple points of contact with the geologic formation to balance the operational forces acting thereon for a desired minimum depth of cut. A moment acting on the rolling element may be minimized to thereby prevent damage to the drill bit. A method for configuring the rolling element may include calculating a critical depth of cut for each point along a radial interval defined by the cylindrical body, changing a design variable, and recalculating the critical depth of cut until at least three contact points exist along the rolling element for a desired minimum depth of cut for the interval.

Title: Processing module for a communication device
Inventor: NICHOLAS BONE
IPC: H04W12/02
Filed: 2020-02-14
Abstract: A communication device receives a current sequence number and a random number from a network entity. If the sequence number is not within a certain range of a previously received sequence number (SQN), this previous number is encrypted and sent in a response message to the network entity. The encryption is performed using a block cipher encryption function and a sequence number encryption key (AK2*), this key having more than 48 bits and being derived from the random number and a key stored in memory at the device. The sequence number may be received in an authentication message of the Authentication and Key Agreement (AKA) protocol. The response may be a synchronisation failure message (resync message). The block cipher encryption function may be a format preserving encryption (FPE) function and the key may have 128 bits. This scheme addresses a potential security vulnerability in the AKA protocol whereby an attacker can prompt multiple resync messages and obtain information about the current sequence number.
